A Science Fiction / Romance film based on the 1995 novel of the same name.
This film provides examples of:
- Adaptation Name Change: Asakura and Yoshizumi's first names are changed from Sachiko and Takashi in the book to Sawako and Takatsugu in the film.
- Composite Character: In this version, Yoshizumi fulfills the role of both himself and Kunio Shinohara from the book as the one who sets Toshiaki up with Kiyomi's liver.
- Compressed Adaptation: The film removes or modifies various aspects of the characters' backstories as shown in the middle part of the book, such as eliminating Mariko's family drama subplot entirely and changing the details of how Kiyomi and Toshiaki met.
- Pragmatic Adaptation: The film makes various changes to the story due to Executive Meddling causing a greater focus on Toshiaki's love story, and making some aspects Lighter and Softer to make them filmable. Toshiaki's attitude towards the humanoid Eve-1 is now one of wistful fascination and desire instead of outright revulsion as it was in the book. The order of the scenes in which Toshiaki encounters her is switched around, with the first now being the sex scene in the cultivation lab, changed from a nightmarish Body Horror scene of rape to a surreal lovemaking scene with a lighter tone. Eve-1 outright spells out her ultimate plan when she gives the address while possessing Asakura, something deemed necessary as in this version, Mariko is not inseminated and Ultimate Eve does not appear, which also changes the reason for Toshiaki's Heroic Sacrifice and means that the other characters who take part in the ending scene are much less worse for wear at the end than in the book.
